CONVEYERFOR SAW-MILL REFUSE.

erEcrr'rcArioN forming part of Letters Patent No. 367,102, dated July26, 1887.

Application tiled January 31, 1887. Serial No. 226,073. (No model.)

and LOUIs NAPOLEON BERGERON, citizens of the United States, residing atStillwater, in

the county of Washington and State of Minnesota, have invented anImprovement in Gonvcyers for Saw-MillRefuse and other Substances; and wedo hereby declare that the following is a full and exact descriptionofthe same, reference being had to the accompanying drawings, makingpart ot' this specitication.

Inv the drawings, Figure 1 represents a top View of a portion ofthetrough, endless chain, and one ofthe sweeps or scrapers'of asawmill-refuse conveyor' provided with our improvement; Fig. 2, alongitudinal vertical section of the saine parts in a plane indicated bythe line xx, Fig. l; Figf. 3, a transverse vertical section thereof inaplane indicated by the line y y, Fig. 1; Fig.` 4, aview in perspectiveofthe part in which our invention consists.

Like letters designate corresponding parts in all ofthe figures.

Our improvement is especially applied to `conveyers for sawdust andother refuse in sawmills; but it is applicable to conveyers of othersubstances or materials, in which an endless chain is used as the meansfor operating the conveyer.

Y Our improvement consists in a double shoe or clasp for uniting thecross sweeps or scrapcrs with the endless chain, whereby thesaid sweepsor Scrapers are held rigidly at right angles to the line of motion, andthis with a single endless chain for drawing the sweeps or scrapers.

In the drawings, A represents a portion of a trough in which the refuseor other material is conveyed; B, one of the sweepsor Scrapers forconveying the same along in the trough, and C an endless chain, to whichthe sweepsor Scrapers are attached, for communicating motion thereto.

In the bottom of the trough A is a sunken channel, a in which theendless chain travels below the sweeps or sera-pers, which slidelaterally over the bottom of the trough. 'The endless chain isordinarily made up of alternate solid horizontal links b b and verticalstrap-'links c c. It is to the solid links, as bb, that the sweeps orScrapers are attached, as represented in the drawings. A

We employ a clasp, D, for each sweep or scraper, by4 which the same isheld rmly at right angles to the trough or line of motion. This clasp isa double one, as shown in Fig. 4, there beingtwo pairs otclasping-langes, d d and ff-one pair, as d d, to clasp against the sidesof the sweep or scraper B, and the other pair, as f f, to clasp againstthe sides of the chain-link b-and the two pairs of ilanges are at rightangles to each other. A single bolt, g, passes down through the middleof the sweep or scraper, the clasp, and the link, and the said parts areheld together by this bolt and a nut, h, screwed upon the bolt. claspmay be made of malleable iron or common cast-iron.

The construction resulting from this improvement is exceedingly simpleand cheap, as well as strong, durable, and effective.

XVe claim as our invention- `In a conveyer, the combination of the claspD, having two pairs' of clasping-fanges with a sweep or scraper, B, andchain-link b, substantially as and for the purpose herein specitied.

In .testimony whereof wevhave hereunto set our hands in the presence oftwo subscribing witnesses.
